Facebook has more than 1.5 billion active advertisers. So it’s
important for Facebook to know what type of ads its users like
seeing on their News Feeds.

On Thursday, Facebook made two
updates that will help it better understand what ads work on its
News Feed.

The first update is asking why
someone’s hiding a specific ad. Facebook so far has given users
the choice to hide an ad if they didn’t like it by clicking on
the top right menu of a post. But with today's update, Facebook
is also asking why someone's hiding a specific ad.

It looks like this:

Facebook said each of the
feedback they receive will be taken into account to decide what
to show on its News Feed. “If someone doesn’t want to see an ad
because it’s offensive, it probably isn’t a good ad for other
people on Facebook, either,” Facebook’s Product Manager Max
Eulenstein
wrote on the company blog.

The second update is that
Facebook will give more weight to feedback from people who rarely
hide ads. “If someone hides things very rarely, we’ll consider
that when we choose what to show them,” Eulenstein wrote. So if
you rarely ever hide ads, and one day decide to give feedback,
Facebook will give more value to your response when deciding what
ads to show on the News Feed.

Today’s updates, however, will
not affect most advertisers, Facebook said. It’s only designed to
control ads that “a small set of people” gave negative feedback
on, and will help advertisers deliver their message more
effectively.
